RESUMO

INTRODUCTION: Colorectal cancer (CRC) ranks as the second leading cause of cancer-related deaths. The PREHAB trial revealed that prehabilitation in colorectal surgery leads to a reduction of severe complications and enhanced functional capacity. Nevertheless, risk selection for prehabilitation and the potential benefits for patients without postoperative complications remains unclear. This study aims to assess postoperative functional capacity, also in patients without postoperative complications. MATERIALS & METHODS: This study was a secondary analysis of the PREHAB trial. Functional capacity tests, including cardiopulmonary exercise testing (CPET), steep ramp test (SRT), 6-min walking test (6MWT), stair climb test (SCT), 30" sit-to-stand test (STS), timed-up-and-go test (TUG), and muscle strength assessments, were conducted at baseline (T0) and 4 weeks postoperatively (T3). The primary outcome was the relative change in functional capacity from baseline to postoperative (ΔT0-T3) per group (i.e., prehabilitation vs control). Secondary, identical analysis were performed for patients without postoperative complications in each group. RESULTS: Intention-to-treat analysis included 251 patients. For postoperative functional capacity, prehabilitation patients showed improvements in VO2peak (p = 0.024), VO2AT (p = 0.017), SRT (p = 0.001), 6MWT (p = 0.049), SCT (p = 0.012), and STS (p = 0.001) compared to the control group. Regarding muscle strength, prehabilitation patients showed improvements in estimated 1RM lateral pull down (p = 0.016), 1RM chest press (p = 0.001), 1RM leg press (p = 0.001) and HGS (p = 0.005) compared to controls. Additionally, prehabilitation patients more often reached baseline levels at T3 in VO2AT (p = 0.037), SRT (p = 0.008), 6MWT (p = 0.013), STS (p = 0.012), estimated 1RM lateral pull down (p = 0.002), 1RM chest press (p = 0.001) and 1RM leg press (p = 0.001) compared to controls. Moreover, even patients without postoperative complications in the prehabilitation group showed better postoperative functional capacity and more often reached baseline levels at T3, compared to controls. CONCLUSION: Multimodal prehabilitation in CRC surgery is associated with improved postoperative functional capacity, even in patients without postoperative complications.

RESUMO

BACKGROUND: Surgery can lead to curation in colorectal cancer (CRC) but is associated with significant morbidity. Prehabilitation plays an important role in increasing preoperative physical fitness to reduce morbidity risk; however, data from real-world practice is scarce. This study aimed to evaluate the change in preoperative physical fitness and to evaluate which patients benefit most from prehabilitation. MATERIALS AND METHODS: In this single-arm prospective cohort study, consecutive patients undergoing elective colorectal oncological surgery were offered a 3- to 4-week multimodal prehabilitation program (supervised physical exercise training, dietary consultation, protein and vitamin supplementation, smoking cessation, and psychological support). The primary outcome was the change in preoperative aerobic fitness (steep ramp test (SRT)). Secondary outcomes were the change in functional walking capacity (6-minute walk test (6MWT)), and muscle strength (one-repetition maximum (1RM) for various muscle groups). To evaluate who benefit most from prehabilitation, participants were divided in quartiles (Q1, Q2, Q3, and Q4) based on baseline performance. RESULTS: In total, 101 patients participated (51.4% male, aged 69.7 ± 12.7 years). The preoperative change in SRT was +28.3 W, +0.36 W/kg, +16.7% (P<0.001). Patients in all quartiles improved at the group level; however, the relative improvement decreased from Q1-Q2, Q2-Q3, and Q3-Q4 (P=0.049). Change in 6MWT was +37.5 m, +7.7% (P<0.001) and 1RM improved with 5.6-33.2 kg, 16.1-32.5% for the various muscle groups (P<0.001). CONCLUSION: Prehabilitation in elective oncological colorectal surgery is associated with enhanced preoperative physical fitness regardless of baseline performance. Improvements were relatively larger in less fit patients.

RESUMO

INTRODUCTION: Increasing evidence suggests that multimodal prehabilitation programs reduce postoperative complication rates and length of stay. Nevertheless, prehabilitation is not standard care yet, also as financial consequences of such programs are lacking. Aim of this study was to analyse clinical outcomes and effects on hospital resources if prehabilitation is implemented for patients who are planned for colorectal surgery. MATERIALS AND METHODS: Patients undergoing elective colorectal surgery and who received either prehabilitation or standard care between January 2017 and March 2022 in a regional Dutch hospital were included. Outcome parameters were length of hospital stay, 30-day postoperative complications, 30-day ICU admission, readmission rates and hospital costs. RESULTS: A total of 196 patients completed prehabilitation whereas 390 patients received standard care. Lower overall complication rates (31 % vs 40 %, p = 0.04) and severe complication rates (20 % vs 31 %, p = 0.01) were observed in the prehabilitation group compared to standard care. Length of stay was shorter in the prehabilitation group (mean 5.80 days vs 6.71 days). In hospital cost savings were €1109 per patient, while the calculated investment for prehabilitation was €969. CONCLUSION: Implementation of a multimodal prehabilitation program in colorectal surgery reduces postoperative complication rates, length of stay and hospital costs.

RESUMO

OBJECTIVE: Current recommendations suggest that patients with newly presenting arthritis suspected of rheumatoid arthritis (RA) should undergo routine radiographs of hands and feet (X-HF) as the presence of RA-associated erosions might be of diagnostic and prognostic value. Our objective was to investigate the prevalence, diagnostic, and prognostic value of RA-associated erosions seen on routine X-HF in a large, recent cohort of patients with newly presenting arthritis. METHODS: A retrospective cohort study was performed between 2016 and 2019 in patients with newly presenting arthritis suspected of RA. Patients were included if arthritis was present at diagnosis, rheumatoid factor and anticitrullinated protein antibodies were measured, RA was noted in the differential diagnosis, and routine X-HF were conducted. Outcomes were the prevalence of one or more RA-associated erosion(s), and whether diagnostic or prognostic classification were changed by erosivity. Seronegative patients, patients without acute phase reactants, and patients with longer symptom duration were analyzed as subgroups. RESULTS: RA-associated erosions were found in 32 of 724 patients (4.4%, 95% confidence interval [95% CI] 3.1-6.2). Erosions led to a change of diagnostic classification in two patients (0.3%, 95% CI 0.01-1.1) and changed prognostic classification in three patients (0.4%, 95% CI 0.1-1.3). Seronegative patients and patients without elevated acute phase reactants had significantly lower prevalence of erosions (χ2 9.4, P = 0.002, χ2 6.5, P = 0.01). Longer symptom duration was not associated with a different prevalence of erosions (χ2 0.4, P = 0.81). CONCLUSION: The recommendation of conducting routine X-HF in patients with newly presenting arthritis suspected of RA might be reconsidered due to low prevalence of early erosive disease and lack of diagnostic and prognostic value.

RESUMO

PURPOSE: This study aimed to investigate the association of effort-independent variables derived from the preoperative cardiopulmonary exercise test (CPET) with 30-day postoperative complications after elective colorectal surgery. METHODS: A multicenter (n=4) retrospective explorative study was performed using data of patients who completed a preoperative CPET and underwent elective colorectal surgery. The preoperative slope of the relation between minute ventilation and carbon dioxide production (VE/VCO2-slope) and the oxygen uptake efficiency slope (OUES), as well as 30-day postoperative complications, were assessed. Multivariable logistic regression analyses and receiver operating characteristic (ROC) curves were used to investigate the prognostic value of the relationship between these preoperative CPET-derived effort-independent variables and postoperative complications. RESULTS: Data from 102 patients (60.1% males) with a median age of 72.0 (interquartile range 67.8-77.4) years were analyzed. Forty-four patients (43.1%) had one or more postoperative complications (of which 52.3% general and 77.3% surgical complications). Merely 10 (9.8%) patients had a general complication only. In multivariate analysis adjusted for surgical approach (open versus minimally invasive surgery), the VE/VCO2-slope (odds ratio (OR) 1.08, confidence interval (CI) 1.02-1.16) and OUES (OR 0.94, CI 0.89-1.00) were statistically significant associated with the occurrence of 30-day postoperative complications. CONCLUSION: The effort-independent VE/VCO2-slope and OUES might be used to assist in future preoperative risk assessment and could especially be of added value in patients who are unable or unwilling to deliver a maximal cardiorespiratory effort. Future research should reveal the predictive value of these variables individually and/or in combination with other prognostic (CPET-derived) variables for postoperative complications.

RESUMO

BACKGROUND: The preoperative period can be used to enhance a patient's functional capacity with multimodal prehabilitation and consequently improve and fasten postoperative recovery. Especially, non-small cell lung cancer (NSCLC) surgical patients may benefit from this intervention, since the affected and resected organ is an essential part of the cardiorespiratory fitness. Drafting a prehabilitation programme is challenging, since many disciplines are involved, and time between diagnosis of NSCLC and surgery is limited. We designed a multimodal prehabilitation programme prior to NSCLC surgery and aimed to conduct a study to assess feasibility and indicative evidence of efficacy of this programme. Publication of this protocol may help other healthcare facilities to implement such a programme. METHODS: The multimodal prehabilitation programme consists of an exercise programme, nutritional support, psychological support, smoking cessation, patient empowerment and respiratory optimisation. In two Dutch teaching hospitals, 40 adult patients with proven or suspected NSCLC will be included. In a non-randomised fashion, 20 patients follow the multimodal prehabilitation programme, and 20 will be assessed in the control group, according to patient preference. Assessments will take place at four time points: baseline, the week before surgery, 6 weeks postoperatively and 3 months postoperatively. Feasibility and indicative evidence of efficacy of the prehabilitation programme will be assessed as primary outcomes. DISCUSSION: Since the time between diagnosis of NSCLC and surgery is limited, it is a challenge to implement a prehabilitation programme. This study will assess whether this is feasible, and evidence of efficacy can be found. The non-randomised fashion of the study might result in a selection and confounding bias. However, the control group may help putting the results of the prehabilitation group in perspective. By publishing this protocol, we aim to facilitate others to evaluate and implement a multimodal prehabilitation programme for surgical NSCLC patients. TRIAL REGISTRATION: The current study is registered as NL8080 in the Netherlands Trial Register on the 10th of October 2019, https://www.trialregister.nl/trial/8080 .

RESUMO

Importance: Colorectal surgery is associated with substantial morbidity rates and a lowered functional capacity. Optimization of the patient's condition in the weeks prior to surgery may attenuate these unfavorable sequelae. Objective: To determine whether multimodal prehabilitation before colorectal cancer surgery can reduce postoperative complications and enhance functional recovery. Design, Setting, and Participants: The PREHAB randomized clinical trial was an international, multicenter trial conducted in teaching hospitals with implemented enhanced recovery after surgery programs. Adult patients with nonmetastasized colorectal cancer were assessed for eligibility and randomized to either prehabilitation or standard care. Both arms received standard perioperative care. Patients were enrolled from June 2017 to December 2020, and follow-up was completed in December 2021. However, this trial was prematurely stopped due to the COVID-19 pandemic. Interventions: The 4-week in-hospital supervised multimodal prehabilitation program consisted of a high-intensity exercise program 3 times per week, a nutritional intervention, psychological support, and a smoking cessation program when needed. Main Outcomes and Measures: Comprehensive Complication Index (CCI) score, number of patients with CCI score more than 20, and improved walking capacity expressed as the 6-minute walking distance 4 weeks postoperatively. Results: In the intention-to-treat population of 251 participants (median [IQR] age, 69 [60-76] years; 138 [55%] male), 206 (82%) had tumors located in the colon and 234 (93%) underwent laparoscopic- or robotic-assisted surgery. The number of severe complications (CCI score >20) was significantly lower favoring prehabilitation compared with standard care (21 of 123 [17.1%] vs 38 of 128 [29.7%]; odds ratio, 0.47 [95% CI, 0.26-0.87]; P = .02). Participants in prehabilitation encountered fewer medical complications (eg, respiratory) compared with participants receiving standard care (19 of 123 [15.4%] vs 35 of 128 [27.3%]; odds ratio, 0.48 [95% CI, 0.26-0.89]; P = .02). Four weeks after surgery, 6-minute walking distance did not differ significantly between groups when compared with baseline (mean difference prehabilitation vs standard care 15.6 m [95% CI, -1.4 to 32.6]; P = .07). Secondary parameters of functional capacity in the postoperative period generally favored prehabilitation compared with standard care. Conclusions and Relevance: This PREHAB trial demonstrates the benefit of a multimodal prehabilitation program before colorectal cancer surgery as reflected by fewer severe and medical complications postoperatively and an optimized postoperative recovery compared with standard care.

RESUMO

OBJECTIVES: In patients with RA treated with (ultra-)low-dose rituximab (RTX), we investigated the association of dosing and timing of RTX on seroconversion after a third coronavirus disease 2019 (COVID-19) vaccination and the persistence of humoral response after a two-dose vaccination. MATERIAL AND METHODS: In this monocentre observational study, patients from the COVAC cohort were included in the third vaccine analysis if humoral response was obtained 2-6 weeks after a third vaccination in previous non-responders and in the persistence analysis if a follow-up humoral response was obtained before a third vaccination in previous responders. Dichotomization between positive and negative response was based on the assay cut-off. The association between the latest RTX dose before first vaccination, timing between the latest RTX dose and vaccination and response was analysed with univariable logistic regression. RESULTS: Of the 196 patients in the cohort, 98 were included in the third vaccine analysis and 23 in the persistence analysis. Third vaccination response was 19/98 (19%) and was higher for 200 mg RTX users [5/13 (38%)] than for 500 and 1000 mg users [7/37 (19%) and 7/48 (15%), respectively]. Non-significant trends were seen for higher response with lower dosing [200 vs 1000 mg: odds ratio (OR) 3.66 (95% CI 0.93, 14.0)] and later timing [per month since infusion: OR 1.16 (95% CI 0.97, 1.35)]. Humoral response persisted in 96% (22/23) and 89% (8/9) of patients who received RTX between the two measurements. CONCLUSIONS: Repeated vaccination as late as possible after the lowest RTX dose possible seems the best vaccination strategy. A once positive humoral response after COVID-19 vaccination persists irrespective of intercurrent RTX infusion. Study registration.

RESUMO

OBJECTIVES: Rituximab (RTX) is a safe and effective treatment for RA. A dose-dependent infection risk was found in the REDO trial. Some studies associate RTX use with higher infection risks, possibly explained by low immunoglobulin levels and/or neutropenia. Additionally, a higher infection risk shortly after RTX infusion is reported. The objectives of this study were (i) to compare incidence rates of infections between doses and over time, and (ii) to assess B-cell counts, immunoglobulin levels, neutrophil counts and corticosteroid/disease modifying rheumatic drug use as mediating factors between RTX study dose and infection risk. METHODS: Post hoc analyses of the REDO trial were performed. Infection incidence rates between RTX dosing groups and between time periods were compared using Poisson regression. A step-wise mediation analysis was performed to investigate if any of the factors mentioned above act as a mediator in the observed dose-dependent difference in infection risk. RESULTS: The potential mediators that were investigated (circulating B-cell counts, immunoglobulin levels, neutrophil counts and drug use) did not explain the dose-dependent infection risk observed in the REDO trial. Additionally, a trend towards a time-dependent infection risk was found, with higher infection rates shortly after RTX infusion. CONCLUSIONS: These secondary analyses of the REDO trial confirmed the observed dose-dependent infection risk. Additionally, we found that infection risks were higher shortly after RTX infusion. However, a mediating pathway was not found.

RESUMO

OBJECTIVES: Humoral response to vaccines in RA patients treated with rituximab (RTX) in standard dosages (≥1000 mg) is decreased. Ultra-low dosages (500 or 200 mg) may have better response. Also, timing after latest RTX infusion may be an important variable. We aimed to investigate the influence of RTX dosage and timing on response to COVID-19 vaccination in RA patients. METHODS: A single-centre observational study (n = 196) investigated the humoral response, measured by total Ig anti-COVID-19 assay (positive response ≥1.1), 2-6 weeks after complete COVID-19 vaccination. A multivariable logistic regression model was built to study the effect of RTX dosage and time between latest rituximab and vaccination on response, adjusting for age and methotrexate use. RESULTS: After two-dose vaccination, the response rate was significantly better for patients receiving 200 mg (n = 31, 45%) rituximab compared with 1000 mg (n = 98, 26%; odds ratio 3.07, 95% CI 1.14-8.27) and for each additional month between latest rituximab and vaccination (OR 1.67, 1.39-2.01). CONCLUSION: Both increased time between latest rituximab infusion and complete vaccination, and 200 mg as latest dose were associated with a better response to COVID-19 vaccination and should be considered when trying to increase vaccine response after rituximab in RA patients.

RESUMO

The clinical benefit of Deep Brain Stimulation (DBS) is associated with electrode positioning accuracy. Intraoperative assessment of clinical effect is therefore key. Evaluating this clinical effect in patients with dystonic head tremor, as opposed to limb tremor, is challenging because the head is fixed in a stereotactic frame. To clinically assess head tremor during surgery, surface electromyography (EMG) electrodes were bilaterally applied to the sternocleidomastoid and cervical paraspinal muscles. This case shows that intraoperative polymyography is an easy and useful tool to assess the clinical effect of DBS electrode positioning.

RESUMO

BACKGROUND: The 'Prediction Of Survival in Advanced Sorafenib-treated HCC' (PROSASH) model addressed the heterogeneous survival of patients with hepatocellular carcinoma (HCC) treated with sorafenib in clinical trials but requires validation in daily clinical practice. This study aimed to validate, compare and optimize this model for survival prediction. METHODS: Patients treated with sorafenib for HCC at five tertiary European centres were retrospectively staged according to the PROSASH model. In addition, the optimized PROSASH-II model was developed using the data of four centres (training set) and tested in an independent dataset. These models for overall survival (OS) were then compared with existing prognostic models. RESULTS: The PROSASH model was validated in 445 patients, showing clear differences between the four risk groups (OS 16.9-4.6 months). A total of 920 patients (n = 615 in training set, n = 305 in validation set) were available to develop PROSASH-II. This optimized model incorporated fewer and less subjective parameters: the serum albumin, bilirubin and alpha-foetoprotein, and macrovascular invasion, extrahepatic spread and largest tumour size on imaging. Both PROSASH and PROSASH-II showed improved discrimination (C-index 0.62 and 0.63, respectively) compared with existing prognostic scores (C-index ≤0.59). CONCLUSIONS: In HCC patients treated with sorafenib, individualized prediction of survival and risk group stratification using baseline prognostic and predictive parameters with the PROSASH model was validated. The refined PROSASH-II model performed at least as good with fewer and more objective parameters. PROSASH-II can be used as a tool for tailored treatment of HCC in daily practice and to define pre-planned subgroups for future studies.

RESUMO

BACKGROUND: Previous studies have suggested body composition as a predictor of sorafenib toxicity and outcome in patients with advanced hepatocellular carcinoma (HCC). Large studies on the impact of body composition parameters in European HCC patients are lacking. Our aim was to validate the prognostic value of body composition parameters in Dutch patients with HCC treated with sorafenib. PATIENTS AND METHODS: A retrospective analysis was performed in a cohort of HCC patients treated with sorafenib at two Dutch tertiary referral centers between 2007 and 2016. Body composition (adipose and skeletal muscle tissue) was measured at baseline by computed tomography (CT). Low skeletal muscle mass (SMM) and density were defined using published cut-offs. Body composition parameters were correlated with overall survival (OS), time to progression, response rate, and toxicity. RESULTS: A total of 278 patients were included, mostly Child-Pugh class A (85%) and Barcelona Clinic Liver Cancer (BCLC) stage C (73%), with a median OS of 9.5 months (95% CI 8.1-11.0). Patients with combined low SMM and low total adipose tissue index (TATI) (n = 68, 25%) had a poor median OS (5.8, 95% CI 4.8-6.8) compared with other patients (11.7, 95% CI 9.4-14.0). Combined low SMM and low TATI remained an independent predictor of OS (HR 1.56, 95% CI 1.15-2.11, p = 0.004) after adjusting for known prognostic factors. There was no association between body composition and sorafenib toxicity. CONCLUSIONS: In Dutch HCC patients treated with sorafenib, the combined presence of low SMM and low TATI was associated with impaired survival, independent of known prognostic factors. CT assessment of body composition may provide additional prognostic information prior to sorafenib treatment.

RESUMO

BACKGROUND: Biliary Cystadenomas (BCA) are considered to be benign but may transform to Biliary Cystadenocarcinomas (BCAC). The aim of this systematic review was to assess the diagnostic work-up and necessity of complete surgical resection. METHOD: A systematic literature search was performed in Embase.com, Medline (Ovid), Cochrane Central, Web-of-Science and Google Scholar. Articles reporting on diagnostic work-up or outcome of various treatment strategies were included. RESULTS: Fifty-one articles with 1218 patients were included: 971 with BCA and 247 with BCAC. Patients with BCA were more often female (91% vs 63.8%, p < 0.001). On radiologic imaging BCAC more often had calcifications (p = 0.008), mural nodules (p < 0.001) and wall enhancement (p < 0.001). Reported treatment strategies were resection, enucleation, or fenestration/marsupialization. Recurrence was reported in 5.4% after resection for BCA and 4.8% after resection for BCAC. Recurrence after fenestration/marsupialization varied from 81.6% to 100% for both BCA as BCAC. Mortality rate was 0 in patients with BCA and 24% in BCAC. CONCLUSION: Due to the difficulty in accurately diagnosing these biliary cystic lesions and the availability of different surgical approaches, patients with suspected BCA or BCAC should be treated in a center specialized in liver surgery with state-of-the-art imaging and all surgical techniques to prevent mismanagement of this rare disease.

BACKGROUND: Multiple tumor foci of intrahepatic cholangiocarcinoma (ICC) are often considered a contra-indication for resection. We sought to define long-term outcomes after resection of ICC in patients with multiple foci. METHODS: Patients who underwent resection for ICC between 1990 and 2017 were identified from 12 major HPB centers. Outcomes of patients with solitary lesions, multiple lesions (ML), and oligometastases (OM) were compared. OM were defined as extrahepatic metastases spread to a single organ. RESULTS: One thousand thirteen patients underwent resection of ICC. On final pathology, 185 patients (18.4%) had ML and 27 (2.7%) had OM. Median survival of patients with a solitary tumor was 43.2 months, while the median survival of patients with 2 tumors was 21.2 months; the median survival of patients with 3 or more tumors was 15.3 months (p < 0.001). Five-year survival was 43.3%, 28.0%, and 8.6%, respectively. The median survival of patients without OM was 37.8 months versus 14.9 months among patients with OM (p < 0.001); estimated 5-year survival was 39.3% and 10.6%, respectively. In multivariable analysis, the presence of two lesions was not an independent poor prognostic factor for OS (HR 1.19; 95%CI 0.90-1.57; p = 0.229). However, the presence of three or more tumors was an independent poor prognostic factor for OS (HR 1.97; 95%CI 1.48-2.64; p < 0.001). CONCLUSION: Resection of multiple liver tumors for patients with ICC did not preclude 5-year survival: in particular, estimated 5-year OS for resection of two tumors was 28.0%.

RESUMO

BACKGROUND: Upon FDA/EMEA registration for hepatocellular carcinoma (HCC), sorafenib received a broader therapeutic indication than the eligibility criteria of the landmark SHARP trial. This allowed treatment of SHARP non-eligible patients in daily clinical practice. AIM: To assess sorafenib efficacy and safety in SHARP eligible and non-eligible patients, and determine the validity of the current therapeutic indication as described by the FDA/EMEA. PATIENTS AND METHODS: Consecutive patients treated with sorafenib for advanced HCC at two Dutch tertiary referral centers between 2007 and 2016 were analyzed retrospectively. Primary outcome was overall survival (OS). Secondary outcomes were time to progression (TTP), response rate, adverse events and reasons for discontinuation. Outcomes were compared between SHARP eligible and non-eligible patients. RESULTS: One hundred and ninety-three of 257 (75%) patients were SHARP eligible. SHARP eligible patients (9.5 months, 95% CI 7.7-11.3) had a longer median OS than non-eligible patients (5.4 months, 95% CI 3.6-7.1) (log-rank p < .001). SHARP non-eligible patients were more often Child-Pugh B, had higher AST and ALT levels and developed more grade 3-4 liver dysfunction (44 versus 23%, p < .001) during treatment. SHARP ineligibility remained the strongest predictor of OS (HR 1.78, 95% CI 1.32-2.41) and an independent predictor of TTP (HR 1.45, 95% CI 1.05-2.00) in multivariable analysis. CONCLUSIONS: Landmark trial outcomes of sorafenib for HCC are reproducible in daily practice, provided that the SHARP eligibility criteria are respected. Based on the findings of this and previous studies, sorafenib usage should be restricted to Child-Pugh A patients.

RESUMO

Objective: Ultrasonography (US) can be used for treatment decisions in RA patients. This study investigated the added value of US to clinical variables in predicting flare in RA patients with longstanding low disease activity when stopping TNF inhibitors (TNFi). Methods: Cox models with and without using US added to clinical variables were developed in the Potential Optimization of Expediency of TNFi-UltraSonography study. RA patients (n = 259), using >1 year TNFi and csDMARD with DAS28 < 3.2 for 6 months prior to inclusion, were followed for 52 weeks after stopping TNFi. The added value of US was assessed in two ways: first, by the extent to which individual predictions for flare at 52 weeks with and without US differed; and second, by comparing how US information improved the prediction to classify patients at 52 weeks in the low risk (<33% flare), intermediate risk (33-50%) and high risk (50-100%) groups. Results: Although US was predictive of flare at group level (multivariate hazard ratio = 1.7; 95% CI: 1.1, 2.5), individual predictions for flare at 52 weeks with and without US differed little (median difference 3.7%; interquartile range: -7.8 to 6.5%). With US, 15.9% of patients were designated low risk; without US, 14.6%. In fact, 12.0% of patients were US-classified as low risk with/without knowing US. Conclusion: In RA patients with longstanding low disease activity, at time of stopping TNFi, US is a predictor for flare at group level, but at the patient level, US has limited added value when common clinical parameters are used already, though the predictive value of clinical predictors is modest as well.
